Move over, Nigella's burkini – you are so last season. The latest addition to the modest Muslim wardrobe is the ResportOn, a sleek sports hijab designed for female Muslim athletes who like to keep their hair covered while working up a sweat.

She came up with the idea after five Muslim girls were banned from competing in tae kwon do tournaments in Montreal because of their hijabs (the headscarves were considered a health and safety risk). Javad, who doesn't wear a headscarf herself, heard about the ban and figured there must be a way to make it easier for hijab-wearing women to participate in sports.

Made from a white antiperspirant sports fabric, it's a tight-fitting hoodie attached to a turtle-neck T-shirt, with a special opening at the back allowing easy access for wearers to readjust their hair. Each one is custom-made in Javad's Montreal studio, where she was set to design hijab tops for the Iranian women's football team for the Olympics next year – only they've just been banned from a crucial qualifying match by Fifa, which forbids players displaying "political, religious . . . or personal messages".

Javed receives orders from Muslim women all over the world, but also from non-Muslim women and men wanting to keep long tresses out of their faces while exercising. Perhaps we'll see the shaggy-haired Barca captain Carlos Puyol in one soon.
